Desney Tan & Scott Saponas: Your body is a wonder, man

Scott Saponas dazzled the crowd yesterday by playing Tetris with his arm. Correction: not with his arm, on his arm. "If you can play Tetris," joked Sapanas as he maneuvered the falling blocks simply by touching various parts of his arm, "You can pretty much do anything."

Saponas and his colleague Desney Tan both work at Microsoft Research. Their latest project, called Skinput, focuses on allowing richer, more natural ways of interacting with our ubiquitous technology devices. They envision a day when you can change your music, learn a language, even answer email using bioacoustics on the touch-sensitive surfaces of our bodies.

"The human body is an amazing playground of technology interface," says Tan. By interacting with computers in a more natural way, "you become the controller."
